In this study, the scattering strength in zinc oxide (ZnO) powder was enhanced by reducing the particle size. ZnO nanoparticles were synthesized with the precipitation reaction. Through electrophoresis, ZnO powder films were made. By performing photoluminescence experiments, the spatial confinement of laser light in the disordered medium was observed.
